NON-BEEILLABLE BOTTLE.

Specification of Letters Patent.

Application filed November 13, 1909.

Patented Aug. 2, 1910. Serial no. 527,878.

To all whom it may concern:

Be it; known that. 1, Faun lV. Hsansa'r a citizen of the United States, residing at Pelham, in the county of Hillsboro and State of New l-lampshire, have invented certain new and useful Improvements in Non- Refillahle Bottles, of which the following is a specification.

My invention relates to a device to he placed in the neck of a fluid receptacle for the purpose of permitting the lluid to be poured therefrom but of such a construction as to prevent the receptacle from being refilled.

My device relates n'incipally to what are called non-refillable hottles.

It is necessary in such a device, first to till the bottle or receptacle and then to arrange it so that. it can be emptied and cannot again he refilled.

In usin r my device, I first till the bottle and then introduce my device into the neck thereof. It is automatically locked in place and cannot thereafter be removed without. breaking the bottle. The liquid can pass through in one direction, that is from the bottle, but no liquid can be introduced from the outside.

In the drawings, Figure 1 is a section of a bottle in an upright position with my preferred form of device. Fig. 2 shows in section the bottle upside down. Fig. 3 shows in section the bottle with the neck filled with liquid and the body emptv, the bottle being in an upright position. Fig. 4 showsjn section an em )ty bottle upside down immersed in liquid. 1g. 5 shows in section an e'iz pt. bottle on its.sidc partly immersed in liquit In Figs. 1 to 5 some parts, as the bottle and case are shown in section and some parts, as the movable valve parts, not in section. Figs. 6 and 7 show modifications of my device. Fi 8 is a section, looking upward on line Y- of Fig. 1. Fig. 0 is an elevation of my case.

The case A com rises a cylindrical tube preferably of meta which may he cut away on the sides as 20 9.0 as shown in Fig. 9 to reduce the weight. The spring teeth which extend downward below the bottom when they have passed in hehin' the line at the bottom of the bottle neck, and lock the device in place. I may use rubber rings 23 set into grooves in the outside of the case to make a tight joint between it and neck It and to prevent; any liquid from passing in or out of the bottle between the neck and. case.

At the top or outer end of case A, 1 use parallel guard shields 3t) and 31. perforated with holes 32, tlfl so arranged that the holes in one shield do not register with those in the other shield. This is to revent a slender device from being passer through into the inside for the purpose of tampering with the mechanism.

Ne r the inner end of case A, is a valve plate 3% from which rises an annular valve seat. 36. Inside this seat 36, are liquid passu es H5 35 and a central passage 87 through va ve plate 34. I pass valve stem 40, as shown m Fig. 8 through passage 37. Preferably i use a central boss 38 depcudin from shield 34 through which passage 37 a so extends thus forming a guide way for valve stem 40.

At the outer end of stem 40, is a dome shaped head 42 at the bottom of whichis attached an elastic packing rin 43 which is normally in en u ement with seat 36. Thereby a liquid tig it. joint is formed.

The entire valve D should be somewhat heavier than the liquid which is placed or to be laced in bottle C. It is plain that this valve will allow the liquid to flow out. from the bottle butit closed will prevent li aid from being poured into the bottle. "Ins valve is normally closed when the bottle 18 held u ri ht; as shown in Fig. 1.

If he ttle is turned u side down as shown in Fi 2, the weight 0 valve D opens it and the liquid in the bottle readily runs out. Thus the bottle ma be emptied. If the bottle is held upside own however, and if for instance the air inside is exhausted and it; is submerged in a tank of ii aid the liquid could enter were it. not for a p urallty of )ivoted floats F.

.ueh float F is either hollow or is made of material ligh r than water and is shaped like a ham. Each is pivoted at its small and inside case A proxinnlte the dome shaped head 42 of valve I). Each flout. I should have sullicieut buoyancy when innnersed in liquid to overcome the entire we: 'htof valve 1). In the case sup used as the niunl rises in the neck of the ottle, it will 1ft these floats F as shown in Fig. 4 and the floats tit hearing against head 42 will lift the valve In its seat and thus n'evrnt liquid from entering the lmttle. Ii the bottle is held upright and the liquid E is poured into the top, the valve retains its seat by gravity and the llonls rise as shown in Fig. 3; if the hot-this laid on its side and is partly immersed in liquid l: as shown in Fig. 5, the liquid will run into the neck ll but before it has reached the hei id of valve seat. 36 it will begin to Heat wliiehever float. F hap ions to be lowest. As these floats are ma u with protruding inner surfaces where they ltdjnilt the head -12 of valve 1), as they rn-se they close the valve l) as shown.

Instead of the valve shown in Figs. 1, 2, 3, 4, and 5, I may 4150 a valve date 62 with a valve seat (l4 through WlllCl is a circular passage. (,3 and an ordinary ball (1 as shown in Fig. 7. This hall may he of rubber, metal or any other material which is heavier than water. The action is substantially the same.

In place of the floats F, I may use three or more buoyant halls K as shown in Fig. (1. .In such case, I locate above the balls, 11 cortical perforated shield (50, which serves to direct the halls against the head of valve 1), when the bottle islaid on its side in liquid thus closing the valve. This conical perforated shield may he. usml instead of one of the guard shields. 'lhese halls l{ act in the same manner as floats F.

What. I claim as my invention and desire to cover by Letters Patent; is

1. A ll uid container havin a neck, a snhstanthilly tubular case whici fits tightly and is locked in said neck, a plurality of perforated guard shields proximate the outer end of said case, a valve late )roximate the inner end of said case I ia-me with a central guide passage and passages adjoining the guide passe e together with an annular valve seat whict encircles said passages. and a yalve having a central stem in Slttlttblt'. relation with the central guide pas sa e. and havin a dome shaped head and being in operative relation with the valve seat, combined with three or more 1mm sha d buoyant members so pivoted inside sai case as to engage the dome shaped head and to seat; said valve as they move away from the case.

2. A litillltl container havin e neck, a snhstantia ly tubular ease whici fits tightlv and is locked in said neck, a plurality o f perforated .guard shields proximate the outer end of said-ease, a valve )latc )roximate th inner end of said case. iormct with a central gnidn passage and passages adjoining the guide past-.a e together with an annu' lnr valve seat whicli encircles said passages, anda valve having a central stein in slideble relation with a central uide passage and havin a dome shaped and and being in operative relation with the valve seat, combmed with three or more buoyant members so pivoted inside said case as to engage the dome shaped head and to seat. sald valve as they move away from the case.

3. A li uid container having a neck, a suhstantia ly tubuar case which fits tightly and is locked in said neck, a plurality of perforated guard shields proximate the outer end of said case, a valve late )roximate the inner end of said case armed with a central guide passage and )assagm adjoinin r the mide passe e together with an anon ar viilve seat w iich encircles said passages, and a valve having a central stem in slidable relation with the central guide passage and having a dome shaped head and being in operative relation with the valve seat, combined with three or more buoyant members so placed inside said case as to engage the dome. shaped head and to seat Sttltl valve as they were way from the case.

4. A li uid container having a neck, a substantia ly tubular case which fits tightly and is locked in said neck, a plurality of perforated guard shields proximate the outer end of said case, a valve olate roximate theinncr end of said case forme with guide passe es together with an annular valve seat w ich encircles said passages, and a valve in operative relation with said valve seat, combined with three or more buoyant members so placed inside said case an to seat said valve as they move. away from the. case.

In testimony whereof I affix my signature in presence of two witnesses.
